如何解决来自调试信息时的条件
我想从stdout创建一个when条件的任务。 剧本示例:
---
- hosts: localhost
gather_facts: false
ignore_errors: yes
vars:
- dev_ip: '192.168.20.192'
tasks:
- name: checkking ssh status
wait_for:
host: "{{dev_ip}}"
port: 22
timeout: 2
state: present
register: ssh_stat
- name: checkcondition
debug:
msg: "{{ssh_stat}}"
输出的消息是:
ok: [localhost] => {
"msg": {
"changed": false,"elapsed": 2,"failed": true,"msg": "Timeout when waiting for 192.168.20.192:22"
}
}
如果要在字符串ssh_stat.stdout中输入“等待192.168.20.192:22时超时”,我想做一个条件任务。
解决方法
这是您需要的:
---
- name: answer stack overflow
hosts: localhost
gather_facts: false
ignore_errors: yes
tasks:
- name: checkking ssh status
wait_for:
host: 192.168.1.23
port: 22
timeout: 2
state: present
register: ssh_stat
- name: do something else when ssh_stat.msg == "Timeout when waiting for 192.168.1.23:22"
shell: echo "I am doing it"
when: ssh_stat.msg == "Timeout when waiting for 192.168.1.23:22"
输出:
PLAY [answer stack overflow] **************************************************************************************************************************************************************************************
